You can use use Skype, Kakao, Voip on Android or iPhone, etc. to practice talking online with native speakers. The following sites help you find someone who (A) speaks the language you want and (B) wants to learn your language, so you can talk together first in one language, then the other. Both of you will practice at no cost:

After you find someone, you email to decide if you can both use Skype, Kakao or other free connection, set a time and start talking. As with any Internet contact, do not trust they are who they say they are. Do not tell them private information, such as when you will be away from home. Take your birth date and other personal information out of your Skype or Kakao profile. Another site has a good discussion of privacy for language learners and teachers.

Besides these well-organized sites, there are forums with long lists of people, not sorted by language, which are not as useful, though if you need a common language, you may find someone who just posted a request: ESL Teachers, Skype community, or Babelan.
